citizen y of the To all 'whom "it may conccm..

Be -it known that I, WILLIAM FARRELL, a United States, residing atPhiladelphia, in thev county of Philadelphia and State of Pennsylvania,have invented an Electricl Engine; and I do hereby declare the followingto be afull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make andV useYthe saine.

My invention relates to electric motors, especially adapted for use in apower house to run dynamos. y In myiiivention the frame', armature andrheostat of `a motor are all mounted on one revolving--body so lthat'the armature will travel around a stationary track when said bodyrevolves. It is not my intention to interfere with the construction ofthe motor, but Inyidea is to mount theinotor itself upon a revolublebody by which the. revolutions of the armature of the motor areeX-changed on a stationary body for the revolutions of the frame of themotor secured to the revolving body The frame l, of the motor should ofcourse be securely fastened to the revolving body. By placing the motorlin this position, it is givenO an enormous mechanical purchase and liscapable of ,30

making a full revolution around the center without a change or reverseinmovement as\ is required by the piston rod of anengine for example. Themomentum of the revoluble body, which is made solid and heavy, is muchgreater than the band wheel of an engine. Furthermore, the use of mymotor will diminish the load of friction by doing awaywithfcounter-shaft pulleys, belts and beltwtighteners.

My invention consists further in the features` of construction andcombinations of devices hereinafter described and specified in theclaims.

In the accompanying drawings, illustrating the preferred einbodimentofmy invention: Figure 1 is aside elevation of a motor constructed inaccordance with my invention. Fig. 2 is an enlarged plan view showing'the revoluble body in central section. Fig. 3 is an 'enlarged sectionalview taken on the line :zc-w of Fig. 2 looking in the direction of thearrow and showing the con-` struction andarrangement Vof the trolleyengaging the lcircular wires. Fig.' 4' is a broken detailed view showingthe particular construction of the trolley and the arrangel nient of thetwo wheels contactingthereon fwith two-circular wires, and Fig. 5 is aplan view of a modiiiedconstruction, the revoluple body being shown incentral section "as in Fig.' 1. y v

betweenwhich the revoluble body 3 is hung. Said revoluble body may bemounted to freely rotate upon a fixed shaft et as illustrated in Fig. 2or it may beI keyed, as at 5,

shown in Fig. 5. When the 'shaft is revoluble, itfmay be'extended beyondits bear.- ings on the support-S and carry azdri've pulpown may be.taken from the revoluble body by Van auxiliary shaft 8'V carrying apinion 9 engaging an internal gear 1.0 Xed tothe side of saidrevoluble-body as shown in`-Iv*`i,f i;,-`2. either'arrangei'nentthe owerof Vthe motor may be transmitteddirectly from the revoluble body, as forinstance, by a belt 11- mounted'the'reon as illustrated in'Fig, 5, f

A stationary track or gear wheel 12 lis cast on or rigidly securedto oneof the su ports and is Iarranged parallel tothe side face o f therevoluble body. y

An electric motor .13 of any ordinary or inthe revoluble bodyiwitli itsframe or cas- .cured to ,said body. The armature of the motor carries awheel or pinion 15 engaging or meshing with the stationary track or gearwheel 12. By this arrangement, it will be seen that when the armature ofthe motor revolves the pinion 15 will travel around the stationary gearwheel 12 and will cause the body 3 to rotate.

face of the stationary gear are arranged two These Wires are chargedwith electricity through the feed wires19 and 20 which, may be passedthrough the stationary gear and one of which carries a controllingswitch' 21. A trolley 22 is pivotally mounted on the revoluble body andcarries twn wheels 23 and 2&1 contacting respectively with the circularwires 17 and 18. Said wheels are kept pressed against these wires bymeans of a spring- 25v connected at its opposite ends to the revolublebody and trolley. The current collected by the wheels on the trolleyfrom Referring more particularly to the draw-I suitable construction ismounted in a cavity' ing securely bolted as at 14 or otherwise se.

parallel circular wires 17 and 18 respectively.

ings, 1 and 2 designate stationary supports or otherwise iXed to arevoluble shaft 6, as

ley 7,' see Fig.- fwlien the shaft s'iXed,

Supported by brackets 16 on. the inner I 5 2. A device ofthe circularvwires is carried to the motor by means of the wires or connections 26.

From the foregoing description it will be seen that when the switch 21is turned on the 5 current from'a source of supply will pass through thefeed wires 19 and 20,.the circu-l 7lar wires 17 and18, the trolley andits wheels and the wires,26 to .the motor. The armarevolve and the gearcarried thereby begin to travel around the stationary track or gearWheel thereby causing the revolution of the body After said body hasmade a few revolutions it will develop a great mothe rotation of saidrevoluble body.

Where it is desired to .develop a greater .horse power than can beobtained from `the 20 use of a single motor, two or more motors may bemounted on the revoluble'body and connected with the stationary trackand driven in a similar `manner as the single motor. In' Fig. 5 I have`illustrated two motors mounted on the revoluble body. In this `figure Ihave also shown two stationary tracks, one at each side of the revolublebody. The motors in this construction carry pinions on each of the endsof their armatures sov that the pinions at one side engageone-stationary track and those on the other side the other track..

' I am aware that other changes may be made inthe constructionsn shownand described in'this application without departing from theV spiritvorsacrificing the advantages of my invention. I, therefore, do not con-"nine myself to the exact constructions and `arrangements herein setforth. f

As illustrated in Fig. 1, a suitable automaticvrheostat 271, may bemounted on the revoluble body so that the three parts of theelectric'motor are placed on said revoluble body and work together inthe revolution thereof.

I claim:

1. The combination, with a revoluble body,

of a stationary circular track, an electric motor mounted within saidrevoluble body, 0 a wheelY carried by the armature ofsaid ture of' themotor will thereupon begin to mentuni vwhich will require only a smallvpower vderived from the motor to continue body being mounted on -ahorizontal engine l Y shaft,means for transmitting power from saidshaft, an electric motor mounted within said revolublebody, a gear wheelsecured to the armature of said motor, a stationary circular trackadjacent to said revoluble body, said gear wheel engaging said track,

and means for transmitting an electric crrent tosaid motor as shown andspecified.

4. The combination, with a revoluble body,
